Handmade custom bikes

Cycling feels natural.
Until it doesn’t anymore.

Pain in your knees.
Tension in your back.
Uncertainty when mounting or stopping.

For many people, this is the moment cycling slowly disappears from daily life.

And that’s a shame.
Because in most cases, the problem isn’t cycling itself — it’s a bike that simply doesn’t fit.

Most bikes are designed for an average rider.
But that average doesn’t really exist.

Everyone is different:

• body height and proportions
• strength and mobility
• balance and stability
• existing physical complaints

A bike that doesn’t match your body forces you to compensate.
Over time, this leads to discomfort, fatigue, and loss of confidence.

With a handmade bike, everything starts with the frame.
It determines how the bike feels and performs.

A frame built specifically for your body provides:

• a natural and relaxed riding position
• the correct knee angle without strain
• improved balance and control
• safe and stable mounting and stopping

The difference is immediate:
less tension, more confidence, and a smoother ride.

A properly fitted bike prevents your body from being forced into unnatural positions.

With the right geometry and components:

• knees and hips are relieved
• strain on back, neck, and shoulders is reduced
• fatigue is significantly lowered

Cycling should not be a burden.
It should give you energy.

Most accidents happen at low speed:
when stopping, starting, or losing balance.

A custom-made bike takes this into account:

• lower center of gravity
• better weight distribution
• optimal saddle height
• direct control at a standstill

This creates calmness.
And calmness leads to safety.

A handmade bike is not mass production.
It is a controlled process where every detail matters.

At Astonic, this means:

• full control over design and production
• high-quality materials
• attention to detail in every step
• a bike that not only looks right, but feels right

A truly custom bike is not created in one step.
That’s why we work with three fitting sessions.

1. Intake and initial measurement

We map your body, preferences, and any physical complaints.

2. Mid-build fitting

During the build process, we refine geometry and positioning.

3. Final adjustment

At delivery, we fine-tune everything: posture, components, and ride feel.

The result: a bike that feels like it was always yours.

Being able to keep cycling means:

• staying independent
• remaining active
• relying less on others
• maintaining confidence in your movement

A custom-made bike is not a luxury.
It is an investment in your mobility and quality of life.

This approach is ideal for:

• seniors who want to stay safe and mobile
• people with physical complaints
• riders recovering from injury
• anyone seeking comfort and confidence
• cyclists who want the best possible riding experience

A handmade custom bike is not a small upgrade.
It is the difference between adapting to your bike — or having a bike that adapts to you.

With the right geometry, high-quality materials, and a carefully guided fitting process, we ensure that you:

• ride pain-free
• stay safe
• and remain mobile for years to come
